Descripción
Recent observations show that the number of stars with very low
metallicities in the dwarf spheroidal satellites of the Milky Way is
low, despite the low average metallicities of stars in these systems. We
undertake numerical simulations of star formation and metal enrichment
of dwarf galaxies in order to verify whether this result can be
reproduced with ”standard” assumptions. The answer is likely
to be negative, unless some selection bias against very low metallicity
stars is present in the observations.
